Abstract
An aspect of the of the invention may include the transfer of a block of data from a first memory location to a second memory location in a DRAM. During the transfer of the block of data from the first memory location, if an encryption mode is selected, the data may be buffered, encrypted, and then stored in the second memory location. If a decryption mode is selected, the transferred data may be buffered, decrypted and then stored in the second memory location. If a bypass mode is selected, the data may be buffered and then stored in the second memory location. In this regard, the encryption/decryption operations may be bypassed.
